Abstract
A rotor wing in a fiber-reinforced composite design including fiber layers, in particular for a tail rotor of a rotary wing aircraft, with a rotor blade () that includes a blade skin () and a blade body (-) that includes an aerodynamically effective profile, with a tension-torque-transmission element () connected to it, which is designed in one piece with the rotor blade (), and with fiber layers (-) that extend through the tension-torque-transmission element () and are scarf-join in the rotor blade (), is improved in that the fiber layers (-) extend right through from the tension-torque-transmission element () to the blade body (-). Furthermore, a method for producing the rotor wing is described.
